I've decided to renovate my garden which consists mainly of a few full grown trees and some shrubs and plants. I have two dogs and they're outdoors most of the time. Like most dogs, mine too love digging around and occasionally chewing on some plants. I need help in designing a dog-friendly or rather a dog-proof garden that gives them ample space to move around, yet restricts them from certain flower-beds. How do i achieve this practically as well as aesthetically? Please help.
